OCTAVE W. PETER-SON, OF CHICAGO, ILLINOIS.

ACE'IYLENE-GAS GENERATOR.

19, isos.

To all whom t may concern:

Be it known that I, Ocrnvn IV. PETERSON, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Acetylene-GasGenerators, of which the following is a specification.

My invention relates to improvements in acetylene gas generators, andhas particular reference to generators for use in connection with thelighting system of automobiles, launches and other isolated structures,as described in my prior application, Serial No. 355,400, filed February2, 1907, whereof this application is a division.

Among the salient objects of my present invention is to provide a carbidbasket and support of simple and effective construction, arranged forvibration in response to jars of the containing receptacle, toconstitute in practice an automatic sieve for screening consumed carbidparticles out of the basket.

Other and further objects of my invention will become apparent to thoseskilled in the art from the following description taken in conjunctionwith the accompanying drawings, in which;

Figure l is a perspective view with parts broken away, of an embodimentof my invention in a structure as described in my aforesaid application;Fig. 2 is a central vertical section through the carbid basket, and;Fig. 3 is a plan View thereof.

In the drawing A indicates in general a cylindrical water receptacle,and B a larger carbid receptacle, the former being detachably superposedupon the latter.

A joint between the water receptacle A and the carbid receptacle B ispreferably formed by the conjunction of an exterior grooved ring a onthe lower edge of the cylinder A and in integral ring d, at the top ofthe carbid receptacle B, and suitable locking devices 5 are preferablyprovided for retaining the receptacles in associated relation.

Suitable means for securing a regulated flow of water from thereceptacle A into the receptacle B, such for instance as described in myprior application, but not herein specifically shown, are provided, andthrough the water receptacle A extends a tube 6 opening at its lower endthrough the bottom of the Water receptacle to the carbid chamber, and atits upper extremity having a hose nipple 7 of any suitable construction.

Specification of Letters Patent.

Original application filed February 2, 1907, Serial No. 355,400. ividedSerial No. 473,162.

Patented May 10, 1910.

and this application led January The ring Z has inwardly projectingtherefrom at one side of the receptacle B, a pair of parallel hooks 8whereon is suspended from one side only a carbid basket generallyindicated at 9. The basket preferably consists of an annular band orbody 10 of sheet metal having its upper edge rolled into a rim 11, andits lower end covered with a screen bottom 12, of wire gauze or likeforaminous material, said body 10 having made therein vertical slots 13conforming in position with the hooks 8, so that the rim at the upperedge of the basket may rest upon the hooks. Thus the basket is supportedwholly at one side of the casing, near the top thereof, in a manner topermit its pivotal movement.

For yieldingly maintaining the basket in a suitable position other thanthat to which it tends gravitationally to assume, I provide a leafspring 14- fiXed to the basket body 10 between the slots 13 andextending downward to bear against the side of the casing or receptacleB, and normally under tension suflicient to maintain the carbid basketnearly horizontal, in operative or sustained position, the action of thespring 14C being preferably reinforced by the action of the spiralspring 15, inserted and suitably secured between the leaf spring 14 orother relatively fixed point on the casing immediately below the pivotalpoints 8, and at its other end coacting with the lower portion of thebasket, preferably with a recess 16, formed in the lower edge of thebasket body 10. Owing to this manner of suspension of the basket 9 it isobvious that the basket willv vibrate with the slightest jars of thereceptacle, and thus, when employed on an automobile, launch, or inother environments where it is constantly subjected to jars, the basketwill serve as a continuous automatic sieve to screen the consumed carbidparticles therethrough on to the bottom of the receptacle B.

The operation of the basket, in its movement, is to toss the carbid andthereby gradually rotate or turn the mass, thus continuously bringingthe larger granules to the top and the smaller powdered particles to thebottom.

Having described my invention, what I claim is:

1. In a gas generator, a carbid receptacle, and a basket having aforaminous bottom, a pivotal support for said basket, and a springbetween the basket and a substantially stationary part, at one sidethereof, to substantially balance the weight of the basket and permit itto move in response to jars.

2. In a gas generator, a carbid receptacle, a carbid basket therein,pivotally suspended from one side only, said basket having a foraminousbottom and a spring interposed between said basket and the wall of thereceptacle, acting to sustain the basket in operative position.

3. In a gas generator, a carbid receptacle, a carbid basket therein,hooks at one side of the receptacle suspending the basket at one sideonly, and a yielding connection be tween the basket and the receptaclepositioning said basket in the casing for vibration upon its suspensionhooks in response to jars.

4. In a. gas generator, a carbid receptacle, having an internalsuspension hook, a carbid basket supported at one side only on saidhook, for pivotal movement thereon, and a spring yieldingly holding saidbasket in sustained position in the casing to vibrate in response tojars.

5. In a gas generator, a carbid receptacle, a carbid basket therein,fixed means pivotally supporting the carbid basket at one side only, aleaf spring interposed between the carbid basket and the receptacletending to hold the carbid basket in raised position, and an expansioncoiled spring interposed between the lower end of the basket and thereceptacle.

6. In a gas generator, a carbid receptacle, a pair of suspension hookscarried thereby, a carbid basket having a pair of spaced vertical slotstherein receiving said hooks, a vertically disposed leaf spring carriedby the basket between the slots thereof, and an expansion coiledcushioning spring carried by the basket and engaging the leaf springadjacent its free end.

7. In a gas generator, a carbid receptacle, a carbid basket suspendedfrom its upper end at one side thereof from said receptacle, theremaining sides of the basket being free of connection with thereceptacle so as to be freely movable and a spring below the suspensionpoint of said basket tending to assist the vibrations thereof.

S. In agas generator, a carbid receptacle, a carbid basket locatedtherein and spaced from all sides thereof, means suspending the upperedge of the basket from the receptacle, at one side only, and springmeans for yieldingly sustaining the basket in position projecting fromsaid suspension means.

In testimony whereof I hereunto set my hand in the presence of twowitnesses.

FORE BAIN, MARY I?. ALLEN.
